o trated as applied to a machine of that kind,

but it is to be understood that in its more general aspects it islikewise applicable to machines for lasting the toes of shoes.

In machines of the above-mentioned charlfact-er the end-lasting wipersare operated by advancing them bodily lengthwise of the shoe and closingthem toward each other laterally of the shoe. An object of the presentinvention is to improve, under some conditions of shoe manufacture, theresults of the lasting operation performed by such wipers, especially atthe sides of the shoe bottom at and near the forward ends of the wipers,and more particularly to avoid any undue dispiacement lengthwise of theshoe of the marginal portion of the upper materials in those locations.To this end the invention pro vides novel means for operating the wipersin such manner as to eliminate, at least for the most part, advancingmovement of the wipers lengthwise of the shoe when operating on portionsof the upper comparatively remote from the end face of the shoe, theconstruction shown being such that the wipers are advanced and closedsimultaneously to Wipe the margin of the upper inwardly around the rearportion of the heel seat while only beginning to wipe it inwardly at theforward end of the heel seat, and are then further closed withoutadvancing movement to complete the overwiping operation. The forward endportions of the wipers accordingly perform most of their operation onthe upper without any bodily advance of the wipers lengthwise of theshoe. so that there is no danger of objectionable forward displacementof portions of the upper materials, in-

cluding the wings of the counter, near the shank portion of the shoebottom. To operate the wipers in the above-described manner, the

machine herein shown is provided with members that are movableindependently of each other to advance and to close the wipersrespectively, these members, as illustrated, comprising slides whichcarry rolls engaged and operated by a single cam that moves the slidesin such time relation to duce the desired results. The constructionshown is further such that prior to the beginning of the simultaneousadvancing and closing movements of the wipers over the shoe they receiveadvancing movement only, to bring them close to and, it may be, a littleover the edge of the rear end of the heel seat.

The novel features of the invention will now be more particularlydescribed by reference to the accompanying drawing and pointed out inthe claims.

In the drawing,

Fig. 2 is a diagrammatic View illustrating the shape of theWiper-operating cam and its relation to the rolls that it engages; and

For purposes of illustration the invention is herein shown as applied toa machineof the type disclosed in Letters Patent No. 1,852,015, grantedon April 5, 1932, upon an application of Jacob C. Jorgensen. As morefully disclosed therein, the machine comprises, for wiping the marginalportion of the heel end of an upper inwardly into lasted position over asole or insole on a last, a pair of wipers curved to embrace the heelendof the upper and formed to extend forwardly at the sides of the heelseat at least as far as the beginning of the shank portion of the shoebottom when the wipers are in fully advanced and closed positions. Thesewipers are supported on a member or slide 12 which is movable to advancethem bodily lengthwise of the shoe, and by curved guiding connections 14more fully disclosed in the above-mentioned Letters Patent they aremounted for swinging movements about an axis located near the rear endof the heel seat to close them inwardly toeach other as to pro-' wardeach other laterally of the shoe. For imparting the swinging or closingmovements to the wipers there are provided slides 16, one for eachwiper, mounted on the frame of the machine for movements laterally ofthe shoe, each slide having an end portion 18 provided with a slot 20 inwhich is mounted a roll 22 carried by the adjacent wiper. The slots 20extend lengthwise of the shoe to permit advancing movement of the wipersrelatively to the slides 16. Each of the slides 16 carries a rack bar 2eengaged by a pinion 26 which is engaged and operated by a curved rack 28formed'on one end of a bell-crank lever 30 pivoted at 32 on the frame ofthe machine, the other end of this lever having thereon a curved rack34; engaged and operated by a rack bar 36. These various parts, asillustrated, are all substantially as disclosed in the above-mentionedLetters Patent.

I For purposes of this invention the two rackbars 36 are carried by awiper-closing member or slide 38 which is operated independently of thewiper-advancing slide 12.

" The wiper-advancing slide 12 carries a roll 40 engaged and operated bya path cam 12 formed in a rotatable cam wheel A and arranged similarlyto the wiper-operating cam shown in the above-mentioned Letters Patent.In the construction herein shown the wiperclosing slide 38 is providedwith a roll 46 "engaged and operated by the same cam 42 that operatesthe slide 12. This cam, as shown in Fig. 2, has an inclined portion awhereby. operative movements are imparted to the wipers through thedifierent rolls and slides. It will be observed that in the operativemovement of the cam its inclined portion a first engages and acts on theroll 40 to impart advancing movement lengthwise of tlie 'shoe to theslide 12 and the wipers before it arrives in position to impart anymovement to the slide 38. Thereafter, in the continued movement of thecam, its inclined por-' tion operates on both rolls 40 and 416 to impartsimultaneous advancing and closing movements to the wipers. In itsfurther movement the inclined portion of the cam ceases to operate theslide 12 while continuing its'operation of the slide 38, so that thewipers are closed inwardly toward each other without any advancingmovement lengthwise of the shoe. With reference to the operationsperformed on the shoe, the construction is such that the wipers arefirst moved substantially half-way along their path of advance withoutany closing movements, thus bringing their wiping edges to the positionsindicated by broken lines at b in Fig. 1 in which they may, asillustrated, slightly overlap the rear end of the heel seat. The wipersthen receive simultaneous advancing and closing movements to wipe themargin of the upper inwardly around the rear portion of the heel seatwhile only beginning to wipe it inwardly at the forward end of the heelseat near the shank portion of the shoe bottom, their positions at theend of these movements being illustrated at 0. At this point they havereceived substantially half of their closing movements. After the wipershave arrived in these positions their closing movements are continuedwithout any advancing movement to complete the overwiping operation atthe sides of the heel seat, as illustrated at d. It will thus be seenthat the wipers perform the greater portion of their operation on theupper at the forward end of the heel seat near the shank without anysubstantial bodily advancing movement lengthwise of the shoe. Theportions of the upper materials, including the wings of the counter,which are operated upon by the forward end portions of the wipers arethus wiped inwardly over the heel seat widthwise of the shoe withoutdanger, on any work, of objectionable forward displacement of thematerials. This not only results in a well-lasted heel seat, but avoidsthe possibility of conditions such as might detract from the bestresults in the lasting of the shankportion of the shoe near the heelseat.

It will be evident from the foregoing description that the desiredresults are obtained without the necessity for any modification of thewipers themselves, which may be constructed as heretofore inheel-seat-lasting machines of the type disclosed in the Letters Patentreferred to, or of other types, and that the changes necessary in suchmachines to accomplish the end in view are comparatively simple andreadily effected. It will further be evident, as hereinbefore suggested,that in its more general aspects the invention is not limited toheel-seat-lasting machines, but is likewise'applicable to ma.- chinesfor lasting the toe ends of shoes in which it may, under someconditions, be utilized with desirable results.
